Struct TextRange 

pub struct TextRange {
    pub start: u32,
    pub end: u32,
}

Represents a range in the source text identified by byte offsets.

Fields

start: u32

end: u32

Implementations

impl TextRange

pub fn new(start: u32, end: u32) -> Self

pub fn len(&self) -> u32

Returns the length of the range in bytes.

pub fn is_empty(&self) -> bool

Returns true if the range has a length of zero.

pub fn overlaps(&self, other: &TextRange) -> bool

Checks if this range overlaps with another.

We consider touching ranges as overlapping (e.g. 0..5 and 5..10 overlap at 5). This strictness is required to prevent ambiguity in insertion order (e.g. which insertion happens first at offset 5?).

Zero-length ranges (insertions) at the boundary of another range are also considered overlapping (e.g. insert at 5 overlaps with 5..10).

pub fn contains(&self, offset: u32) -> bool

Checks if this range contains a specific offset.

Trait Implementations

impl Clone for TextRange

fn clone(&self) -> TextRange

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TextRange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TextRange

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<T> for TextRange

where T: RangeBounds<u32>,

fn from(r: T) -> Self

Converts to this type from the input type.

impl Hash for TextRange

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TextRange

fn eq(&self, other: &TextRange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TextRange

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
